My wife is using this sub 500 buck unit -> http://s175.photobucket.com/albums/w146/rproffitt2000/?action=view¤t=480.jpg for powerpoint and more. It's quite nice for the price. If we ever want a pump it up a little we'll get a 2GB RAM upgrade.
It's no gaming machine but does play DVDs, multimedia and more.
What's the best budget desktop replacement/multimedia laptop(under $1500) out there?
